TO ALL WHOM IT MAY CONCERN:

Be it known that I, CHARLES SPoEEoRD, of Boston, in the county ofSuffolk, and State of Massachusetts, have invented an improvedAdjustable Cutting-Die, of which the following is afull, clear, andexact description, reference beinghad to the accompanying drawings,making part'of this specification, in whioh-' Figures l, 2, and 3 areperspective views, representing thc male and female portions of myadjustable dic for cutting paper collars.

Figure 4 is a longitudinal section, and

Figure 5 a transverse section, representing the two dies in a positionfor cutting out the collar.

My invention relates particularly to certain improvements in a die forcutting paper collars, for which Letters Patent of the United Stateswere granted to George K. Snow, on the 28th day of November, A. D. 1865.His said invention consisted ina pair of dies, the adjustments of which,to adapt them to cut collars of varying sizes, were'performed withdiiculty, and consumed much time, owing t0 their complicatedconstruction and theirl position in the machine, while the outer-endsonly of the collars were cut by them, the division of'one collar fromanother on the line forming the lower edge of one and the upper edge ofthe other, being performed by another die or cutter at a separate andsubsequent operation. 1 A

My invention consists in a single die, which cuts out the entire collar,or other article of paper, or other material at a single operation, themale portion of the die being composed lof sections, which are securedto the plunger, the outer sections being moved and adjustedlongitudinally to and from each other, andthe space between them beingoccupied by a block of the size required to form the collar of the rightlength, while the female portion of the die is also formed in sections,so that its size may be varied to correspond with that of the maleportion of the die, by which construction I avoid the expense incurredin making separate dies for each size of article to be out, in a moresimple andv convenient manner than bythe employment ofthe dies referredto in the above-mentioned patent. l y t To enable others skilled `intheart to understand and, use my invention, I will proceed todcscribe-the manner in which I have carried it out. v l A In the saiddrawings, Awrepresents the head of the plunger, to which is screwed themale portion B of a die for cutting paper collars, composed of threepieces or sections, C C D,a longitudinal strip, a, serving as a guide,being interposed between the sec-tions and the plunger, to admit of theouter sections C C being slid thereon to obtain the length of collarrequired, suitable slots, b, and screws c, being provided to enable theworkman to secure the sections immovablyin place when adjusted, thespace e f between them being iilled by a. block, D, fig. 2, which isfastened to the guide a by a screw, g, and is readily removed therefromto allow a block, E, of a diie'rent size being substituted therefor.(See fig. The upper and lower lines hz' and k Z of the die,corresponding tothe upper and lower edges of the collar, are madestraight, and parallel to each other, and the construction of the guideon which they slide is made to correspond thereto, but when a collar isrequired whose upper and lower edges are curved, itis simply necessaryto employ a curved guide. The female portieri ofthe die consists of twoend pieces, H, resting on a bed-piece, I, provided with an opening, m,whose width is equal to v the width of the male portion B of tlie'die,and consequently that of the collar to be cut. Steel strips .I K arescrewed firmly to the bed-piece, and serve as ways, within which the endpieces I-I are made to slide longitudinally, so that they may be fittedsnugly to the male portion B, after it has been adjusted to agiven sizeof collar, the female portion,when fitted, being pressed against thestrip .I by set-screws n, thus preventing any lateral displacement, andbeing held down immovably upon the bed-piece by bolts o passing throughslots and tightened by screw-nuts r. lhe edge L z' of the severalsections composing the male portion of the die is slightly bevelled, asshown in figs. 2, 3, and 5, to insure a shearing cut.

Instead of constructing'the male portion B of the die in sections, itmay be made in one piece, and a die i of al different size be employed,whenever a collar of diiercnt size is required, the female portion onlyof the die being made adjustable. l

I have referred in the above description to a die for cutting papercollars, but itmay be, cons.ructed in any form to adapt it for cuttingont a variety of articles,`either in metal, cloth,.or other material.

I C'Zaz'm.

What I claim as my invention, and desire to secure by Letters Patent, isThe within-described adjustable die, constructed substantially as andfor the purpose set forth.
